If, as planned, the United States eventually establishes a lunar base in 2020, one of the most tempting patches of moonscape is Shackleton Crater at the south pole.

There may be water ice for drinking or converting to rocket fuel, the nearly constant sunlight at the rim is ideal for solar power, and the temperature is relatively bearable.

But perhaps the most compelling reason is something far more primal: surviving the lunar night, which lasts 14 Earth days and can hit temperatures so cold that oxygen turns to liquid. - Christian Science Monitor
